Install should be used to load a memory resident program into memory just prior to
starting the application that requires the memory resident program. If a memory
resident program is loaded into memory using the AUTOEXEC.NT file, the memory
resident program will be loaded into memory every time the command prompt is
started, wasting memory.

Do not use Install to load programs that use environment variables or shortcut keys or that
require CMD.EXE to be present to handle critical errors.
